Perched high above the rooftops of the East 60s, Residence 21A is a truly one-of-a-kind home, enveloped by expansive terraces and framed by breathtaking open skyline views to the east, north, and west. Sunlight pours into the residence throughout the day, from the first light of sunrise to the glow of sunset, creating a warm and inviting atmosphere rarely found in city living. Currently configured as a gracious two-bedroom residence with separate living and dining rooms, as well as a dedicated full-size laundry room, the home's unique double-corner layout offers exceptional flexibility. Whether maintained in its current form or reimagined as a three-bedroom residence, the floor plan can easily adapt to a variety of lifestyles and needs. Beyond its remarkable privacy and tranquility, this home showcases a timeless level of craftsmanship, with thoughtful design and custom finishes evident in every room. The chef's kitchen is both elegant and highly functional, featuring granite countertops, sleek stainless-steel cabinetry, a Capital five-burner range with convection oven, a garbage disposal, and premium Sub-Zero and Miele appliances. The primary bath serves as a private retreat, beautifully finished in Porcelanosa Kathmandu stone and appointed with a deep soaking Jacuzzi tub, a Thermasol steam shower, integrated sound and video, and an expansive slate vanity. The secondary bath is equally distinctive, wrapped in polished steel penny tile and complemented by a black Caesarstone countertop and a shower with a fold-down teak seat. A fully outfitted laundry room with Miele washer and dryer, along with custom stainless steel shelving, adds convenience without sacrificing style. Life at The Rio Condominium and Spa offers a level of service and amenities more akin to a boutique hotel than a traditional condominium. Residents enjoy the benefits of a full-service building with a 24-hour doorman, live-in superintendent, and full-time porters. The building's exceptional spa facilities include a fitness center, heated swimming pool, hot tub, steam room, and sauna. A beautifully landscaped rooftop terrace provides panoramic city views, while private storage adds further convenience. The Rio is pet-friendly, welcomes pied-à-terre ownership, and permits corporate and foreign purchasers. Ideally situated near transportation, shopping, dining, and some of the city's leading hospitals, Residence 21A offers an extraordinary opportunity to enjoy luxury living in one of Manhattan's most desirable neighborhoods.
